Causes and measures (tree of life)

Why does thuja turn yellow?

There are a number of causes that cause the tree of life to turn yellow or have yellow tips.

• Location too humid / too dry
• Nutritional deficiency
• Overfertilization
• Pest infestation
• Fungal diseases

The tree of life is very robust, so Diseases and pests are less common. Mostly care errors or location errors are responsible for the yellow discoloration of the needles.

Incorrect care of the thuja

Thuja likes a slightly moist soil without waterlogging. Dries the earth is out, the tips turn yellow and then brown. More often helps here to water. In the event of waterlogging, it is essential to ensure that the soil is better drained.

Often the gardener means it too well by that Fertilize. This is a real problem, especially with mineral fertilizers. Over-fertilization is just as harmful to the thuja hedge as too few nutrients.

Rather rely on organic fertilizers such as compost,

Horn shavings(€ 32.93 at Amazon *) and crap. Mulch blankets made from bark mulch are also good for the supply of nutrients.

Yellow tips due to lack of magnesium

The tree of life is not very demanding. However, if there is a lack of magnesium, the tree turns yellow. Fertilizing with Epsom salt can help. However, you should first take a soil sample and have it examined in the laboratory.

If there is a magnesium deficiency, fertilize the hedge with it Epsom salt. You have to follow the dosage instructions exactly. Over-fertilization with Epsom salt leads to acidification of the soil, which also weakens the thuja.

Epsom salt can either be sprayed in liquid form or sprinkled on the floor in solid form. The tops and bottoms of the leaves are sprayed. Do not spray directly on the trunk. You also shouldn't fertilize on a very sunny day.
